Sparc update

I found the annoying bug that sometimes prevented any disk access. This was because the IOMMU page table alignment restriction (32k) was satisfied in virtual memory level, but not physical. Depending on the compilation options, phase of moon etc. ESP memory access didn't work. Now I tried several compilers, switches and debug options and every version produced works. The rest of the patch fixes some warnings (GCC 4.1) and changes over to switch_context method at boot. Some newly enabled filesystem code needed more bits from libgcc. No progress with Linux. _________________________________________________________________ Express yourself instantly with MSN Messenger!

There was a bug in obp_nextprop, zs devices need to be mapped, and ESP needed an interrupt.

SILO loads Linux
by Blue Swirl 15 May '06

15 May '06

Today I got SILO to load Linux from CD, aliasing sd(x,y,z). I also made the boot less noisy by default. SILO file is given as hda, cd image as hdb: 3 > boot disk [sparc] Booting file 'disk' with parameters '<NULL>' Unknown filesystem type Not a bootable ELF image Unknown filesystem type Not a Linux kernel image Unknown filesystem type Loading a.out image... Loaded 96912 bytes entry point is 0x4000 Jumping to entry point... SILO No config file loaded, you can boot just from this command line Type [prompath;]part/path_to_image [parameters] on the prompt E.g. /iommu/sbus/espdma/esp/sd@3,0;4/vmlinux root=/dev/sda4 or 2/vmlinux.live (to load vmlinux.live from 2nd partition of boot disk) Your imagename `:d' and arguments `' have either wrong syntax, or describe a label which is not present in silo.conf Type `help' at the boot: prompt if you need it and then try again. boot: sd(0,1,0)/boot/sparc32.gz Unknown filesystem type Uncompressing image... PROMLIB: obio_ranges 1 SILO can browse the filesystem, load sparc32.gz, uncompress it and start Linux. Linux fails as before. I feel that if partition access worked, booting directly from disk would be easy. CD support needs some block size confusion solved, maybe even in Qemu. What is the syntax used for accessing partitions, is it not like .../sd@0,0:a for first partition? _________________________________________________________________ FREE pop-up blocking with the new MSN Toolbar - get it now! http://toolbar.msn.click-url.com/go/onm00200415ave/direct/01/

I added a.out executable format support, which is used for prom-bootable files. Now SILO loads if a complete file is given as hda. There are problems with device opening and block loading, and the partition offset has no effect. We also need to support the ancient sd(controller, unit, lun) syntax. 3 > boot disk [sparc] Booting file 'disk' with parameters '<NULL>' Unknown filesystem type Not a bootable ELF image Unknown filesystem type Not a Linux kernel image Unknown filesystem type Loading a.out image...
